Product Information
Full details
The Morse Taper (MT4) Revolving Live Centre is designed for professional machinists and woodworking hobbyists who require high-precision support for workpiece stabilization on a lathe. Its primary benefit is the integration of a heavy-duty, sealed triple-bearing system that maintains concentricity under load, allowing for smooth, high-speed turning operations. While it provides exceptional stability for metal and wood turning projects, users should be aware that it requires proper lubrication and regular maintenance to sustain its precision performance over time.

FAQs
Can I use this on a mini-lathe?
Most mini-lathes utilize an MT1 or MT2 taper. This is an MT4 centre and will only fit lathes specifically equipped with an MT4 tailstock.
Is this suitable for metalworking?
Yes, it is designed for both metalworking and woodworking, provided the equipment is MT4 compatible.
What is the maximum load capacity?
The live centre is rated for a radial load capacity of 600kg.
How do I remove the centre from the tailstock?
Most lathes feature a self-ejecting tailstock; retract the quill fully until the centre pops out, or use a drift key if the lathe is so equipped.
Does it need regular grease?
The bearings are sealed, so it does not require frequent internal greasing, but keep the exterior clean and free of corrosion.
What is the top speed rating?
The unit is rated for operation up to 3800 RPM.
Troubleshooting
Visible vibration during rotation
Check that the workpiece is mounted correctly and the live centre is firmly seated in the tailstock taper.
Excessive heat generation
Reduce the rotational speed or check if the tailstock pressure is set too high, which may be causing excessive friction.
Difficulty inserting into the tailstock
Inspect the taper for nicks, burs, or accumulated debris and clean both the tool and the tailstock hole thoroughly.
Pros and Cons
Pros
- Capable of supporting heavy workpieces up to 600kg
- Triple bearing design ensures high accuracy and stability
- Suitable for both wood and metal lathe operations
- High-speed rating of 3800 RPM accommodates diverse project needs
- Sturdy construction minimizes vibrations during use
Cons
- Requires periodic maintenance and lubrication
- Heavy weight may be challenging to handle during quick setup changes
- Not intended for non-MT4 compatible lathe machines
- High precision makes it sensitive to heavy impact damage
Setup, Compatibility & Care
To install, first clean the internal taper of your lathe tailstock and the exterior taper of the live centre with a dry cloth to ensure a secure, debris-free fit. Insert the MT4 shank into the tailstock quill and seat it with a firm push or a light tap from a soft-faced mallet.
For care, wipe the unit down after every use to remove metal chips or wood debris. Although it features sealed bearings, applying a light machine oil to the point or the seal area periodically can help prevent rust and maintain smooth rotation. Avoid exposing the centre to extreme heat, as this can degrade the internal grease and damage the seals.
